Reserved.
FIFO Size — RO (Input stream), R/W (Output stream). Indicates the maximum number of bytes that
could be fetched by the controller at one time. This is the maximum number of bytes that may have
been DMA’d into memory but not yet transmitted on the link, and is also the maximum possible value
that the PICB count will increase by at one time.
The value in this field is different for input and output streams. It is also dependent on the Bits per
Samples setting for the corresponding stream. Following are the values read/written from/to this
register for input and output streams, and for non-padded and padded bit formats:
Output Stream R/W value :
NOTES:
Input Stream RO value :
NOTE: The default value is different for input and output streams, and reflects the default state of
1. All other values not listed are not supported.
2. When the output stream is programmed to an unsupported size, the hardware sets itself to the
3. Software must read the bit field to test if the value is supported after setting the bit field.
